Application fileti April 2. 1953 To all whom it may concern a citizen ofthe United States, residing; at Vi ashington, in the District ofColumbia, have invented certain new and useful Improvements in ElectricLights, of which the following is a specification, reference being badtherein. to the accompanying drawing.

This invention relates to lights, and more particularly to an electriclight attachment for battery cells.

The principal object of the invention resides in the provision of anattachment of simple construction which may be easily attached to orremoved from the battery cell.

Another object consists in forming the at tachment from a blank ofmetal. adapted to be pressed and bent to form an arm for connecting tothe cell, a socket for the light bulb, and. reflector.

A. further object consists in novel means for swinging the attachmentfor making or breaking a contact and the provision of means forconnecting the attachment to a plurality of cells if desired.

lVith these and other objects in view, my invention consists in thenovel details of construction and arrangement of parts which will bemore clearly understood from the following specification and drawings.in which Figure l is a side elevation of my attachment connected inposition upon a. cell.

Figure 2 is a top plan.

Figure 3 is a frontelevation of my at tachment, showing only a portionof the cell.

Figure 4 is a plan of the blank from which my attachment is formed.

Figure 5 is a plan of the insulating strip for securing my attachment tothe cell post.

Figure 6 is a side elevation of a slightly modified "form of attachment,with only a portion 01? the cell illustrated.

Figure 7 is a top plan of the modified form of invention.

Figure 8 is a top plan showing the mot ified form of invention used inconnection with two cells.

Figure 9 is a plan of the blank from which the. morflilied term ofattachment is :t'ormed.

In the drawings, the numeral 1 indicates a dry battery cell having thecentral carbon. post 2 and outer zinc post 3. A. binding nut st isreceived upon the threaded end of the Serial No. 270,714..

post 2, and a ljll'lCllng nut 5 is received upon the threaded end of thepost 8.

' In the preferred form of my invention, the attachment is formed from ablank of metal illustrated in F lg. 4t of the drawings. This blankvcomprises a circular body portion 6. having an opening- 7 therein. andan arm 8 having ears 9 formed on opposite edges thereof. intermediatethe ends. The circular portion 6 will be pressed or stamped to form areflector 10,which is bent to ex end at right angles with respect to theend of the arm 8. The arm adjacent the reflector, is bent to form agoose-neck portion 11.. and the outer end of the arm is slightly curvedas shown at 12 for a purpose to be later described.

The ears 9 are adapted to be bent around the side edges. and under thebottom, of a strip 13 Of insulating material. This strip 13 is provided,adjacent one end, with an opening which is reinforced by means of ametal ringll. Bvconnecting the arm 8 to the insulating strip 13. bymeans of ears 9, it will be seen that the arm may be adjusted withrespect to the insulating strip so as to bring; the arm in properposition for forming the contacts to be later described.

An electric light bulb is shown at 1.5 and the threaded end. 16 extendsthrough the opening '7, in the reflector, so that its rounded end 17 maycontact with the upper end of the post 2 or the binding nut as moreparticularly illustrated in Fig. l of the drawings.

The parts will be assembled as illustrated in Fig of the drawings. Thepost .2 will pass through the opening or ring" 14, in the insulatingstrip 13, and by the binding nut 4 will be held in position. The arm 8will be adjusted on the strip 13 so that the rounded end 17. of thethreaded portion 16 of the light bulb to, will contact with either theend of the post or with the binding nut. The goose-neck ll forms aspring for holdingthe rounded portion 17 in coiract with the post ornut. The strip 13 will be loosely held upon the post sothat by grasping"the curved end 12. of the arm the whole attachment may be swung eitherinto the full line position, indicated'in Fig. 2, or into the. dottedline position shown in this figure. l hen swung into the full lineposition the contacts will be broken so that the light will be out. llhen it is desired to light the bulb the arm is grasped and. theattachment swung into the dotted line position with the curved portion12, of the arm 8, engaging the upper end of the post 3. The circuit willthen be completed and the bulb lighted. By curving arm 8, as shown at12, it is placed under tension so that it will be held in close contactwith the end of the post. By again turning the attachment ino the fullline position, the light will be extinguished.

In the modified form of the invention the cell is indicated at 18, thecentral carbon post at 19, and the outer zinc post at 20. A binding nut21 is received on the threaded end 01 the central post 19, and a similarbinding nut 22 on the threaded end ofthe post 20.

In this modified form of invention the attachment is formed from a blankillustrated in Fig. 9. This blank comprises a circular body portion 23having an opening 24, adjacent the edge thereof, and an arm 25 having aplurality of longitudinally spaced openings 26. The circular bodyportion 23 will be pressed or stamped to form a re- Elector 27 which isbent to extend at right angles to the end of the arm 25. The arm 25 willbe curved as indicated at 28 for a purpose to be later described. Anelectric light bulb as indicated at 29 and the threaded shank 30thereof, extends through the opening 24, in the reflector 27, and therounded end 31 is adapted to be brought into contact with the upper endof the post 19 or with the binding nut 21.

In the modified form of the invention, the parts will be assembled asmore particularly illustrated in Fig. 6 of the drawings. The post 20will pass through one of the longitudinally spaced openings 26, in thearm 25 and the bindingnut 22 will be adjusted so as to hold the arm onthe post, but at the same time to allow it to be swung from one side tothe other. W' hen not in use, the arm will be swung into the full lineposition illustrated. in Fig. 7 of the drawings so that the roundedportion 31 of the lamp bulb will not contact with the post 19 or nut21.. When it is desired to light the bulb the attachment is swung sothat the rounded portion 31, of the bulb, will contact with the end ofthe post 19 or the upper face of the nut When in this position the bulbwill be lighted and the light reflected to the desired position by thereflector 27.

In Fig. 8 I have illustrated the modified form of my invention asattached for use with two cells 18. When used with two cells the post 20of one of the cells will pass through the outer opening 26, in the arm25. The binding nut 22 will hold the arm upon the post. The two centralposts will be con nected by means of the wire 32 and to light the bulbthe attachment will be swung so that the rounded end 31 of the bulb willterms a support for the light attachment and when in use the cell may becarried to the desired position, and set so as to reflect the light inany desired position. By having the reflector at right angles withrespect to the arm, the light will be reflected to the side of the cellwhile the cell is supported in vertical position.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent is 1. In combination with a battery havingterminals extending therefrom, a strip of insulating material having anopening to receire one of the terminals, an arm bent intermediate itsends to form a spring, ears formed on the arm for engaging andadjustably connecting the arm to the insulating st up, a reflectorformed on one end ofthe arm, and an electric light bulb carried by thereflector, the bulb adapted to engage one of the terminals and the armthe other, to complete a circuit to illuminate the bulb.

2. In combination with a battery cell having a central contact post andan outer contact post, a strip of insulating material pivotallyconnected to one of the contact posts, an arm adjustably connected tothe insulating strip and adapted to engage the other contact post, saidarms having ears adapted'to engage the edges of the insulating strip,and an electric light bulb carried by the arm and adapted to engage thatpost to which the insulating strip is pivoted.

3. In combination with a battery cell having a central contact post andan outer contact post, a st'ip of insulating material pivotallyconnected to one of the contact posts, an arm connected to saidinsulating strip and bent intermediate its ends to overlie both contactposts, one end of the arm adapted to contact with one of the posts, andthe other end carrying an electric light bulb adapted to contact withthe other post.

In testimony whereof I hereunto afiiX my signature in the presence oftwo witnesses.
